IMPROVEMENT IN SHAVES FOR BOOTS AND SHOES.

Specification forming part of Letters Patent N 0. 138,328, dated April29, 1873 application filed March 31, 1873.

To all whom it may concern:

Be it known that I, DEXTER HARRINGTON,

of the town of Southbridge, county of Worcester and CommonwealthofMassachusetts, have invented certain new and useful Improvements inShaves, designed more especially for use in the manufacture of boots andshoes; and I hereby declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanying drawingwhich forms a part of this specification, and in which- Figure 1represent a plan View of my improved shave. Fig. 2 represents a bottomview, and Figs. 3 and 4 represent views of opposite sides of the same.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe it in detail.

In the drawing, the part marked A is the stock or main frame-piece,which holds the cuttin g-blade B between its upper jaw D and lower one0, each of which has projecting rib-like pieces a c d d, the pieces 0 01being joined at point e, and pieces 0 d at point e, from which pointsproject spur-pieces E E, which, with arms 0 c d d, form handles for theshave. The middle portion of the stock A is curved out so as to conformto the shape of the cutter B, and the handles, at their ends, are curvedslightly backward. Both the inner and lower margins of the upperjaw-piece D are slotted out; in the former case for the ready escape ofthe shavings, and in the latter so as to admitthe cutter is kept inposition, which position is regulated by guide-pieces h h. Another setof screws, H H, pass through the ends of spurpieces E E, and keep thetwo jaw-pieces C and D in proper relative position.

As the knife or cutter B wears or is ground away, the jaws (J and D canbe adjusted nearer together by means of the screws H H to keep the edgeof the cutter at the proper relative position as respects the jaw 0.

It will thus be seen that, by the peculiar combination, with the jaws OD and spurpieces E E, of the screws G G and H H, substantially as shownin the drawing, the cutting-blade can be easily and accurately placed inposition, and afterward adjusted, as it wears or is ground away, to cutany desired thickness of shaving, and that, too, in a most perfectmanner. Then, again, it will be seen that the shave is not only light,but very strong, and, besides, is not liable to get out of order.

Having described my improved boot and shoe shave, what I claim as of myinvention, and desire to secure by Letters Patent, is-

1. The combination, with the jaw-pieces O D, arm or rib pieces 0 d c d,and spur-pieces E E, of the adjusting-screws G G and H H and cutter orshave B, substantially as and for the purposes set forth. j

2. The combination, with the jaw-piece D, of the spur-pieces E E andholding-screws G G, substantially as and for the purposes set forth.
